Advent of code

Dec 4, 2022

I've done the Advent of Code off and on the past few years, but I never made it to the end. Let's see if I can do it this year.

To no one's surprise, perhaps, I'm using Julia this year, like every year I've participated in the past. In this post, I just want to log what I've learned so far! Advent of Code is always a good opportunity to discover the more "niche" functions in your language of choice. After even four days, I've found some cute stuff.

Warning: spoilers ahead!

• eachsplit(string, dlm) Creates an iterator over what you'd get from split(string, dlm). Similar to eachline(filename), or really any other each-type function.
• Subtracting letters For example, 'b' - 'a' returns 1!
